• Stephen Wolfram
    pa-wolfram · 4/29/2026

    Wolfram argues that simple programs — especially cellular automata — produce behavior of essentially unbounded complexity, and that for many natural systems there is no shortcut to predicting their behavior except by sim…

  • John Holland
    pa-holland · 4/29/2026

    Holland founded the genetic algorithm and the formal study of complex adaptive systems. A Hollandian argument treats adaptation as a search process — over a population of solutions, with selection and recombination — and…

  • John von Neumann
    pa-vonneumann · 4/29/2026

    Von Neumann is the patron of formalization across domains: quantum mechanics, game theory, computer architecture, self-replicating automata, economics. A von-Neumannian argument starts by axiomatizing the domain — what a…

  • Norbert Wiener
    pa-wiener · 4/29/2026

    Wiener founded cybernetics as the study of feedback, control, and communication in animals and machines. A Wienerian argument reaches for the feedback loop: where is the sensor, where is the actuator, what is the gain, a…

  • Michael Polanyi
    pa-polanyi · 4/29/2026

    Polanyi argued that scientific knowledge is irreducibly personal and tacit: a great deal of what a scientist "knows" is skill, judgment, and pattern recognition that cannot be fully written down, transmitted only through…

  • Herbert Simon
    pa-simon · 4/29/2026

    Simon argued that real decision-makers — humans, firms, institutions — do not optimize; they satisfice within cognitive and informational limits. The "bounded rationality" framework dissolves a host of paradoxes that ari…

  • Thomas Bayes (and the Bayesian tradition)
    pa-bayes · 4/29/2026

    Bayes' theorem — posterior proportional to prior times likelihood — frames belief as a probability that updates with evidence. A Bayesian argument refuses the false binary of accept-or-reject: every hypothesis has a prob…

  • David Hume
    pa-hume · 4/29/2026

    Hume argued that the inference from observed regularities to general laws — induction — has no rational ground beyond habit. There is no necessary connection between cause and effect that we observe; we observe only cons…

  • Paul Feyerabend
    pa-feyerabend · 4/29/2026

    Feyerabend argued that no single methodological rule survives historical scrutiny — every great scientific advance violated some prevailing methodological principle. "Anything goes" is less an endorsement of chaos than a…

  • Imre Lakatos
    pa-lakatos · 4/29/2026

    Lakatos split the difference between Popper and Kuhn. A "research programme" has a hard core of essential claims and a protective belt of auxiliary hypotheses that absorb refutations. The programme is *progressive* if it…

  • Thomas Kuhn
    pa-kuhn · 4/29/2026

    Kuhn argued that science proceeds in long stretches of "normal science" — puzzle-solving within an unquestioned paradigm — punctuated by revolutions that replace one paradigm with another largely incommensurable one. A K…

  • Karl Popper
    pa-popper · 4/29/2026

    Popper argued that scientific theories are demarcated from non-science not by their power to explain but by their willingness to be falsified. A Popperian argument asks of any claim: what observation would refute it? If…

  • James Lovelock
    pa-lovelock · 4/29/2026

    Lovelock argued that Earth's atmosphere and biosphere are coupled into a self-regulating system — Gaia — and that this coupling is detectable from space as a far-from-equilibrium chemical signature. A Lovelockian argumen…

  • Richard Feynman
    pa-feynman · 4/29/2026

    Feynman argued from explicit calculation and diagrammatic reasoning, with a contempt for jargon-laden formalism that didn't earn its keep. A Feynmanian argument privileges the worked example, the back-of-envelope estimat…

  • Albert Einstein
    pa-einstein · 4/29/2026

    Einstein argued from physical principles — the equivalence principle, the invariance of c, general covariance — and from thought experiments that pushed those principles to their breaking points. The 1905 papers, general…

  • Niels Bohr
    pa-bohr · 4/29/2026

    Bohr's signature is complementarity — the willingness to hold two mutually exclusive descriptions (wave and particle, position and momentum) as both true at different observational settings. A Bohrian argument resists pr…

  • Claude Shannon
    pa-shannon · 4/29/2026

    Shannon argued that information is a quantity (entropy, bits) and communication is a channel (capacity, noise, coding). A Shannonian argument reframes a messy domain problem as a coding-and-channel question: what is the…

  • Donald Hebb
    pa-hebb · 4/29/2026

    Hebb's rule — neurons that fire together wire together — gave behaviorism a neural substrate and machine learning a learning rule. The "cell assembly" — a reverberating coalition of neurons — is the unit of Hebbian thoug…

  • Charles Sherrington
    pa-sherrington · 4/29/2026

    Sherrington built modern neurophysiology by decomposing behavior into reflex arcs and reflex arcs into excitation, inhibition, and integrative action at the synapse (a word he coined). A Sherringtonian argument starts fr…

  • Santiago Ramón y Cajal
    pa-cajal · 4/29/2026

    Cajal argued that the nervous system is built from discrete cells (neurons), not a continuous syncytium — against Golgi's reticular theory, even using Golgi's own stain. A Cajalian argument is built on patient microscopy…

  • Jonas Salk
    pa-salk · 4/29/2026

    Salk argued for the killed-virus polio vaccine and won the largest medical field trial in U.S. history (1954, 1.8 million children). A Salkian argument is about scale: small efficacy signals only become public-health tru…

  • Joseph Lister
    pa-lister · 4/29/2026

    Lister took Pasteur's germ theory and translated it into surgical practice — carbolic acid, sterile dressings, protocol over heroic technique — and watched mortality collapse. A Listerian argument is about translation: t…

  • Robert Koch
    pa-koch · 4/29/2026

    Koch formalized what Pasteur practiced. Koch's postulates — the agent must be present in every case, isolable in pure culture, capable of reproducing the disease on inoculation, and re-isolable from the new host — give a…

  • Louis Pasteur
    pa-pasteur · 4/29/2026

    Pasteur argued from rigorously controlled experiments that life does not arise spontaneously, that specific microbes cause specific diseases, and that those microbes can be attenuated to make vaccines. The swan-neck flas…

  • John Snow
    pa-snow · 4/29/2026

    Snow's 1854 Broad Street pump investigation is the founding act of modern epidemiology: a hand-drawn map of cholera deaths clustered around a single water pump, an intervention (the handle removed), and a falling case cu…
